Jev and Stagehand Browser Use

A remote-browser loop combines Jev action decisions with Stagehand execution.

How it uses Jev

The post describes sending an accessibility tree as state and browser actions as questions to Jev; Stagehand executes the selected next action in a remote browser.

App workflow

  1. Observe page

    Read the page accessibility tree.

  2. Offer actions

    Send the tree as state and available actions as questions to Jev.

  3. Choose action

    Jev decides the next action.

  4. Execute and repeat

    Stagehand performs the action in the remote browser, then the loop observes again.

Why it is interesting

The loop explicitly splits constrained action choice from browser execution, which makes the decision and acting components independently identifiable.

  • CUA-JEV

    Choose and verify constrained computer actions across GUI and structured tools using Jev.

  • Jevry

    Let Jev select grounded browser actions while language models handle planning and explanation.

  • System1 Agents

    Run and evaluate fast decision-model agents for browser tasks, games, robotics, and structured choices.
